Description

This role provisions a nim Codex installation.

Introduction

The role will:

• Checkout a branch from the nim-dagger repo
• Build it using the build.sh Bash script
• Schedule regular builds using Systemd timers
• Start a node by defining a Systemd service

Ports

The service exposes two ports by default:

• 9000 - LibP2P peering port. Must ALWAYS be public.
• 9900 - Prometheus metrics port. Should not be public.

Installation

Add to your requirements.yml file:

- name: infra-role-nim-codex
  src: git+git@github.com:status-im/infra-role-nim-codex
  scm: git

Configuration

The crucial settings are:

# branch which should be built
codex_repo_branch: 'stable'
# optional setting for debug mode
codex_log_level: 'DEBUG'

Management

Service

Assuming the main branch was built you can manage the service with:

sudo systemctl start codex-main
sudo systemctl status codex-main
sudo systemctl stop codex-main

You can view logs under:

tail -f /data/codex-main/logs/service.log

All node data is located in /data/codex-main/data.

Builds

A timer will be installed to build the image:

 > sudo systemctl list-units --type=service '*codex-*'
  UNIT                                LOAD   ACTIVE SUB     DESCRIPTION
  codex-prater-stable.service   loaded active running Codex (stable)

To rebuild the image:

 > sudo systemctl start build-codex-main

To check full build logs use:

journalctl -u build-codex-main.service

Requirements

Due to being part of Status infra this role assumes availability of certain things:

• The iptables-persistent module
